Version 6.0.0

ENHANCEMENTS

• The installer program has been enhanced to support Azul Zulu JRE 11. As a result of this change, the installer has ended support for some of the old operating systems. The installer supports the following operating systems after the enhancement:*
  • UNIX/Linux:
    • Any operating system on a machine using a JRE that is Java SE 8 or higher (LTS version), including Oracle JDK, OpenJDK, and IBM SDK (Java) distributions.
  • Windows:
    • Windows 8.1 or higher
    • Windows Server 2012 RC2 or higher
  Important: These changes do not affect the operating system requirements of the driver.
  
• The driver has been enhanced to support the following types of data types:
  • Geometric types
  • Network address types
  • Monetary types
  • Date/time types
  • Range types
  For details, refer to Data types.
• The driver has been enhanced to support the TXID_SNAPSHOT data type. For details, refer to Data types.
• The driver has been enhanced to include timestamp in the Spy and JDBC packet logs by default. If required, you can disable the timestamp logging by specifying the following at connection: For Spy logs, set spyAttributes=(log=(file)Spy.log;timestamp=no) and for JDBC packet logs,
  set ddtdbg.ProtocolTraceShowTime=false.
• Interactive SQL for JDBC (JDBCISQL) is now installed with the product. JDBCISQL is a command-line interface that supports connecting your driver to a data source, executing SQL statements and retrieving results in a terminal. This tool provides a method to quickly test your drivers in an environment that does not support GUIs.
• The driver has been enhanced to support a customized version of the Greenplum COPY command. It provides an additional keyword, LOCALFILE, to allow you to copy data from or to standard file-system files that are stored anywhere on your network, not just on the database server. For details, refer to Using COPY command.
• The PrepareThreshold connection property has been added to the driver. This property determines the number of PreparedStatement executions that must occur before the driver begins using server-side prepared statements. For details, refer to PrepareThreshold.
• Support for the Kerberos authentication protocol has been added with the following   connection properties: AuthenticationMethod and ServicePrincipalName. For details, refer to AuthenticationMethod and ServicePrincipalName.

CHANGED BEHAVIOR

• The driver does not support access to Pivotal HAWQ anymore.
• The default value for the SupportsCatalogs connection property has been changed to true. For details, refer to SupportsCatalogs.
• Added the RegisterStatementPoolMonitorMBean connection property. Note that the
  driver no longer registers the Statement Pool Monitor as a JMX MBean by default.
  You must set RegisterStatementPoolMonitorMBean to true to register the Statement Pool Monitor and manage statement pooling with standard JMX API calls. For details, refer to RegisterStatementPoolMonitorMBean.
  

Version 5.1.4

ENHANCEMENTS

• The CryptoProtocolVersion connection property has been added to the driver. This property can be used to avoid vulnerabilities associated with SSLv3 and SSLv2, including the POODLE vulnerability.
• Support for result set holdability has been added to the driver.

ENHANCEMENTS

• Added SSL support for Greenplum 4.2, incorporating eight additional connection properties
• Added SupportsCatalogs connection property, which enables driver support for catalog calls
• Added four connection properties to handle VARCHAR, LONGVARCHAR, and NUMERIC data types: MaxVarcharSize, MaxLongVarcharSize, MaxNumericPrecision, and MaxNumericScale
